Pandora Radio at Reception?

My FI and I are having a 1950s picnic with a pig roast at a city park for our reception/party after our courthouse wedding. I want to just use Pandora radio, such as the Buddy Holly station, for the music, since it will give us the right vibe without all the hassle of creating our own playlists. Unfortunely, my FI does not like this idea because we won’t have much control over what is played. As a guest, what you would think about Pandora Radio being used a very casual wedding reception/party?
